Product FAQ

FAQ: What is an Injector’s Static Flow rate?

ERIKC Answer: Manufacturers rate fuel injectors by the maximum amount of fuel that they can flow in a given amount of time at a given pressure. This measurement is known as Static Flow Rate and is normally taken at 100% duty cycle and a fuel pressure of 43.5 PSI.

Example: At 100% duty cycle a 55 pound (lb) injector at 43.5 PSI of fuel pressure will flow 55 pounds per hour.

Injector Flow Rates are expressed in pounds per hour (lb/hr) or cubic centimeter per minute (cc/min). Given the same pressure 1 lb/hr = 10.5 cc/min.

To convert lb/ hr to cc/min, multiply by 10.5

Sometimes injector flow rates are expressed in milliliter per minute (ml/min)

1 ml = 1 cc

Example: a 220 cc injector = 220 ml injector

FAQ: Most injectors fall into two categories: High or Low Impedance

ERIKC Answer: High Impedance.

These have a typical coil resistance of 12 – 16 ohms and are the most commonly used. Drive circuitry for this type of injector is simple and sometimes referred to as a saturated driver circuit.

Low Impedance.

Low Impedance Injectors has normally a coil resistance of 4 ohms or less and is typically found in larger sized or high performance injectors. Driver circuitry for these types is called a Peak - Hold type and is more complex and costs more than the saturated type.
